Any modem recommendation for low SNR? My SNR margin for downstream is less than 10dB and line attenuation for downstream is more than 60dB. I'm currently using Aztech 305E and i get disconnected frequently.

I did some research and i found out that modems using texas instrument chipset can handle low snr better. But i tried my friend's modem, zyxel p-660r (texas instrument), i still cant get a stable connection. But when i tried another modem, aztech dsl-206u (eagle), i found that it is slightly better. Can aztech dsl-600eu handle low snr? or any other recommendation? I really need a new modem.
